CORPORATION OF yIDELAVVAIBE FURNACE CONVEYER 4Original application led April 8, 1926,.Seria1 No. 100,681. Divided and this application filed June 1,

1927; Serial No. 195,766. Y.

My invention relates to furnace equipment, and it has for one object the provision `of a conveyer particularly adapted for. use in high-temperature furnaces of the continuous type.

vide a conveyor wherein the work-supporting surface thereofcomprises the upper edges 'i of a plurality ofv overlapping blades.

A further object of my invention is to provide vconveyer mechanism comprising a flexible belt and a plurality of attachments therefor provided with overlapping `worksupporting blades, the blades beingrnormalY to thebelt by presenting anv inclined face to the line of movement of the belt.

A still further object of my invention isY to provide means, whereby the flexible belt portion of the conveyer may be vshielded from the direct heat ofthe furnace, aswell as .subjected to the effect of cooling means.

Other objects. and applications of,l my invention, as well as details of construction and bladerconve'yer rfor carrying thetreated -articles Vreceived from Athe quenchingtankthrough said drawing furnace to: skids at 4the discharge end thereof; i f

. `As illustrated in Fig. 1, the axles aquenching tank by means of a conveyer .13 say of the sprocket-chain type.y The, axles passing over the Vupper end ofthe conveyer 13 are guided by'means'of a yslide 77 onto an outer end Sof a conveyen The .latter Another object of my invention is to proy K or other articles under treatment may be inovedfrom entersa furnace 11 through an inlet opening 79, passing through a heated chamber section/81, a discharge outlet 14, aroundV sup- Y porting sprocket mechanism 82,` through a cooled section 83 of the furnace 11 and finally around sprocket mechanism 84- positioned externally ofthe furnace but adjacent to the inlet opening 7 9. n In the passage of the axles over the slideway- 77, they are automatically turned7 assuming the position shown in Fig.A

.2, wherein the yokes 23 vinstead of extending downwardly now extend horizontally, so that allv parts of the axle maynbe positioned in the same heat zone and a uniform tempera-V turev thereby acquired. y

The conveyer 12 for carrying the axles in such horizontal position through kthe drawing furnace-11, is particularly ilustrated Figs. 3 to 6, inclusive and comprises a pair of spaced link belts 85 and 86. The sprocket mechanism 82 at the discharge end of theffurnace 11coinprises ya pair of spaced sprocketA the outer ends ofthe link belts85 and. E56-and `are mounted on a common shaft `89. v The lat- 'wheels 87 and 88 which respectively support chain 92 from a driven sprocket wheel 93. n

The sprocket mechanism 84 at theinlet end of the furnaceA 11 is similar to that just described. f i f Experience has shown that the portion of the ,link belts 85 andl Sdin the heated chamber section 81'must be protected from the intense heat, otherwise the belts stretch to the extent of rendering thejconveyer 12 as a whole inoperative. Acordingly, I provide guards 94, and for theportions of the link pasage 97 having a relatively narrow elongated slot 98. v Y

The portion ofthe link belt which extends through the chamber 97may be suitably supported within by means of a member 99`of the form particularly disclosed in Figs. 4, 5

and 6. yEach member comprisesa base portion 101, whichis riveted to a link of the f belt, and downwardly spaced end portions 102 and 103 which slidably engage spaced supporting tracks 104 and 105 vformed on s 107 which is angled with respect to the length of the beltI and positioned in overlapping relation to the similar member on, say, a succeding link of the belt. Since 108 and 109 ofthe blade 107 are flared outwardly from tliebase member 101, sothat a relatively wide blade is formedat the upper end thereof forminga supporting edge 111. LThe members 99 arecso positioned that, as they pass around the sprocket mechanism 82 at the c discharge end of the furnace 11, they do not ible belt, and aY plurality'of attachments l separate sui'liciently to permit an axle to drop therebetween but rather provide a continuous supporting surface. The axles passing through the discharge outlet 14 of the furnace 11 may be, conveyed therefrom by spaced lskids 15 terminating in a receptacle 114.

The'portion of the chain disposed within the chamber 97 may be maintained at a desiredtemperature by a pair of longitudinally extending cooling pipes 115 and 116. The cooling effect of these pipes is limited to the chamber 97 by reason of the relatively small dimensions of the slot 98 andthe fact that the blades 107 extend well abovethe belt guard 94 into the furnace passage 81.

Considering the o eration of my'appara-V tus, the movement o the sprocket chain conveyer 76 carries the axles out the quenching tank and deposits the same on the conveyer 12, causing them to assinne a horizontal position, wherein the yokes 23 are in substan- Vtiallythe same plane as therbody portion 22.

Afterfbeing carried through the drawing furnace 11A by the conveyer 12, the axles are finally deposited on the skids v15 leading to a cart or other receptacle 11a. Y lhile I have shown only one embodiment of my invention,for the purpose of describing the same and illustrating its principles of construction and operation, it is apparentV that variousV changes and modifications may v be made therein without departing from the spirit of my invention, and I desire, therefore, `that only such limitations shall be imposed thereon as are indicated in the ap-` pended claims or as are demanded by the prior art.

I I claim:
